Tiny robot could Stop Bleeding from inside the Body using heat


Tiny robot could stop bleeding from inside the body using heat   Max Planck

A centimetre-sized robot with a soft body and metallic scales inspired by pangolins can stop bleeding or destroy cells from inside the body using heat

A small robot that can shape-shift and produce heat could incinerate cancer cells or stop bleeding from inside the body. It could also be used to ferry drugs directly to tumours or hard-to-reach places like arteries.

Tiny robots with soft bodies have shown promise for delivering drugs without causing damage – but adding hard elements could make them more useful.

Ren Hao Soon at the Max Planck Institute for Intelligent Systems in Stuttgart, Germany, and his colleagues designed the centimetre-sized robot to have overlapping aluminium plates inspired by pangolins, the only mammal with scales. They layered rectangular “scales” over softer, magnetic material, which let the robot change its shape.  ... '
